Fig. 6: Multi-step reactions through droplet merging.
From: Self-synchronization of reinjected droplets for high-efficiency droplet pairing and merging
a Schematic showing the process of droplet merging and the enzymatic reactions within the droplets. b Optical micrograph showing the merged droplets with uniform size and homogeneous quinoneimine. Scale bar: 50 μm. c Graph showing the variation in droplet color intensity with glucose concentration. Two hundred droplets were captured and analyzed at each concentration
